For the last leg of their journey, the team search for the most iconic animal of them all, the tiger. To find it, they must split up. Wildlife camerawoman Justine Evans and the science team head to the tangled jungles of northern Burma, one of the largest swathes of unbroken forest in Southeast Asia. Wildlife cameraman Gordon Buchanan heads to the only other place in Burma where tigers may still exist, the far south. The forests of Karen State were once home to a thriving population of tigers, but this region has been isolated by war for over 60 years and little is known about the fate of the animals. The team must overcome intense physical hardship and tough field conditions to find the evidence they need to help preserve this unique and largely untouched wilderness. What they discover could change the future of Burma's forests forever.

Oxygen – we all need it, we can't live without it. It's integral to life on this planet. And it's probable that, as you watch this film, you will be breathing in an oxygen atom that was also breathed by Genghis Khan – or by the first ever apes to stand upright on the plains of Africa. The oxygen that we breathe is made from two oxygen atoms joined together – O2. They were first joined more than 3 billion years ago by the earliest blue-green algae to evolve. The oxygen molecule first came from bacteria and was present in the fires that destroyed the dinosaurs and the chemical reactions in all human cells, and as ozone they protect the earth from radiation. Since then, both together and apart, they've had the most extraordinary adventures. Each of the two atoms in an oxygen molecule is virtually indestructible – so they have been first-hand players in some of the most dramatic events in the whole of Earth's history. It's often said that we are breathing the same oxygen that the cavemen did. The life of a single molecule of oxygen is traced on it's astonishing journey spanning millions of years, from its creation, into photosynthesis, through the age of the dinosaurs, early man, and on into today.

David Attenborough has a passion for birds' eggs. These remarkable structures nurture new life, protecting it from the outside world at the same time as allowing it to breathe. They are strong enough to withstand the full weight of an incubating parent and weak enough to allow a chick to break free. But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.
